Description

PDF

This is a Backpacking Inflator for a Therm-a-Rest backpacking mattress like the x-lite.  It is very lightweight and therefore somewhat fragile.  Take care.  I recommend printing the body with a 0.4mm nozzle in PETG and the impeller with a 0.2mm nozzle in PLA.  To assemble this you need several parts.  They are linked here
